What is déjà vu?  Many of us know the feeling. You’ll be going about your day, minding your own business, folding some laundry…nothing out of the ordinary.

Suddenly a sensation of familiarity washes over you, and you’re completely aware that it’s happening. I’ve been here before. Except you haven’t. Or have I? You might try to think back and pinpoint when you’d experienced this moment before. But just as quickly as the feeling hits you, it’s gone again.

Did you predict the future? Were you seeing something from a past life? What is déjà vu, anyway?
